“Your data center is so cool!”
That’s the common reaction to web-IT data center networks architected for data-intensive workloads and unprecedented agility. Clos designs optimized for east-west traffic flows and standard layer 3 protocols with ECMP have replaced brittle 3-tier Cisco-style layer 2 networks. DevOps with a true Linux network operating system (AKA “NetDevOps”) enables secure, reliable configuration management and automated lifecycle management while converging on a common set of tools and processes across compute, storage, and networking. What’s really cool is the high speed interconnects in fat tree network designs.
10G and 40G leaf/spine networks were the standards last year. This year, 25G connected hosts and 100G spines are emerging as the desired interconnect, aligned with the latest Xeon-based servers with Broadwell cores. With the 25/50/100G inflection, many new merchant silicon entrants have hit the market, and Cisco announced proprietary ASICs for the Nexus 9200/9300 with availability at the end of the year. But, why wait? 25/50/100G Spectrum-based switches from Mellanox with Cumulus Linux are available now.
The joint Mellanox Spectrum and Cumulus Linux solution enables an open platform, unlocked performance, and unleashed innovation. Cumulus Linux is based on an open framework enabling customers of all Continue reading

In this video, Tony Fortunato explains why it’s important to baseline your network troubleshooting tools.
Managing cloud resources together with on-premises data centers is making life hard for IT teams.
A while ago I guestimated that most private clouds don’t have more than a few thousand VMs, and that they don’t need more bandwidth than what two ToR switches could provide.
Last autumn Iwan Rahabok published a blog post describing the compute- and storage parts of it, and I had a presentation describing the networking aspects of high-density consolidation. However…
